Cow Milk Specific Gravity at $60^{\circ}\text{F}$

Specific gravity is a measure of density, comparing the density of a substance (in this case, cow milk) to the density of water at a reference temperature.

The standard specific gravity for cow milk, measured at $60^{\circ}\text{F}$ (approximately $15.6^{\circ}\text{C}$), is generally found to be within the range of 1.028 to 1.030. This range can vary slightly depending on factors such as the milk's fat content, total solids, and temperature variations.

Therefore, the correct range reflecting the specific gravity for cow milk at $60^{\circ}\text{F}$ is 1.028 to 1.030.
